I was wondering if anyone else has had this problem--- 
I just started using a BE112 from Best ecig about a month ago. From what I understand emailing with them, it is basically the same as the 801.  I like the cig, but the batteries, one is dead, (have already received a replacment) the other has gotten to a point where air will not pass thru it.  Right now, I have seven batteries, three are usable, the other four well,  let's just say they are in questionable condition.  I am waiting to hear back from Best about the problem.
Am I missing something here? Is this a common problem. I realize when you draw, air has to pass through the battery, doesn't it? Well it feels liek the battery has gotten plugged up, The atomizer is clear, it draws air nicely, so does te cart itself, but very little air passes through the battery.
Any help or suggestions will be appreciated.
Thanks for any help.
